Thanks I will look into it. Not having an angle drill is what was holding me back from this.SuperHerman wrote: ↑Thu Jul 05, 2018 9:54 pmYou should be able to buy a tap set for about $10 - or the specific tap for a few bucks. Don't give up on a proper repair so easily. You could blow a leak in a year and be out in the middle of no where. Just not worth it.
You just need to pull up the specs for the existing bolt and the proposed bolt. Take a look at this as a starting point:

Drilling through the coolant pipe is pretty easy - just remove the gasket, tape up the hole and drill. If you have to borrow an angle drill or angle drill adapter (you can get these at Mendards) and you should be able to do it in car. A flexible shaft adapter would also be an option for drilling out the coolant pipe.
This sounds like the best scenario. It would be great to not have to see the cylinders for a little while.
